Depends on the pipeline architecture... but judging by the similar pipeline performance in the present cards? Yeah, if true, it's probably close to 50% faster than an 8x1 card! But the die size would make them really expensive... of course, with Doom3 packaged with new nvidia cards, that would offset the cost a bit

The pieplines give you the basic fill rate of a card, but other things like memory bandwidth and hardware features like PS andVS can restrict the speed quite a bit (and AA and AF too).

I keep getting a lot of mixed info. See most of these sites that talk about the 16 pipelines only say NV4x. The problem is the NV45 is supposed to come out later this year and was supposed to have 16. I'm wondering if people are getting these two cards mixed up. I did hear mention of something like 220M transisters, so it could be true.

That is pretty unfortunate if they consume that much power. I think with Intel pushing to increase the TPD of Socket T, we will already be experiencing some power supply deficiencies. I'd imagine an NV40 paired with a 3.6ghz prescott will consume so much power that you will probably need a quality 500W PS as a bare minimum. Then there is the whole thermal management issue. BTX should help, but it looks as though the large fans will have to be pretty powerful to vent 200-250W of heat. It will be like running a server from your bedroom.

Man that would suck. I read that even the Antec power supplies at 550 really did not put out much above 500w. Todays power supplies will really struggle. If it does use 150w it is going to make the dust buster cooling look mild compared to what this beast will need.

Originally posted by MuFu Well it'll need a couple of Molex feeds and AGP power from a fat PSU or have it's own power supply ("Voodoo Volts" anybody?).

MuFu.

GeForceFX already requires both AGP and molex power. But that's the direction it's going- with video cards literally turning into miniature PCs in their own right, their power consumption is going up as fast as CPU consumption. And heat... 150W is just ridiculous! I mean, how the hell are we supposed to cool that? There's no way that's true- it would never make it to production if it were.

That is still insane. Of course some of that is likely from the memory, so it might be 100w for the GPU. That will still need a mighty heatsink to keep cool. I still have images of the FX Cool system on the original GeforceFX 5800 Ultras and the funny pictures of people using them as leaf blowers and hair driers and articles saying they sounded like a vaccume cleaner inside their case when they powered up.
